A solo practice with a single focus: your books.
Duvell Bookkeeping Services is owned and operated by one bookkeeper — so the person you hire is the same person doing the work, answering your questions, and standing behind every report.
Every email, every reconciliation, every monthly report — handled directly by the owner.
Built to give small business owners back their time and their confidence.
Most small business owners didn't start their company because they love reconciling accounts. They started it because they're great at what they do — and the books quickly become the part nobody looks forward to.
That's where Duvell Bookkeeping Services comes in. As a solo practice, the focus is simple: accurate books, on-time reports, and a real person you can actually reach. No layered teams, no junior staff learning on your file, no surprises at year-end.
Whether you need ongoing monthly bookkeeping, a clean QuickBooks setup, or help catching up after months — or years — of falling behind, the work is done personally, carefully, and with the long-term health of your business in mind.

Meet the Founder
My name is Antonio Sullivan, and I'm the founder of Duvell Bookkeeping Services.
Since 2013, I've built my accounting career by working my way from entry-level accounting positions to corporate accounting responsibilities. Throughout my career, I've had the opportunity to support organizations in hospitality, nonprofit, education, and administrative environments, gaining hands-on experience with bank reconciliations, accounts payable, accounts receivable, payroll, invoicing, financial reporting, and month-end close processes.
Those experiences taught me that every successful business depends on accurate financial records, organized systems, and reliable support. They also showed me that business owners need more than someone to record transactions—they need someone they can trust.
That's why I founded Duvell Bookkeeping Services.
My mission is to bring order to financial chaos by combining professional bookkeeping, responsive service, and modern technology to help business owners make informed financial decisions and grow with confidence.
When you work with Duvell Bookkeeping Services, you're not simply hiring a bookkeeper—you're partnering with someone who values accuracy, integrity, responsiveness, and long-term business relationships.
